SPECIFICATION forming part of Letters Patent No. 769,750, ated September13, 1904.

Application filea December 19,1903. Serial No. 135,797. (No model.)

To all whom, it may concern.-

Be it known that I, FREDERICK G. KUNE, a citizen of the United States,residing at the city of New York, borough of Brooklyn,county of Kings,in the State of New York, have in vented a certain new and useful\Vater-Purifier, of which the following is such a full, clear, and exactdescription as will enable any one skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

The object of my invention is to construct an electrolyticwater-purifier which will effectively subject the water to the action ofthe current and at the same time will allow a large quantity of water topass through the purifier, so that the purification will be rapidlyaccomplished.

Another object of my invention is to construct the purifier with thefewest possible joints and to make the necessary joints perfectlywater-tight.

My invention consists in part in the combination, with a plurality ofconduits having a common inlet and a common outlet, said conduits beingimperforate between said inlet and outlet, of means for subjecting thewater while flowing through said conduits to the action of an electriccurrent.

My invention also consists in various other novel features and detailsof construction, all of which are described in the followingspecification and pointed out in the claims affixed hereto.

In the accompanying drawings, which illustrate one form of purifier madein accordance with my invention, Figure 1 is a side elevation, theelectric circuit being shown diagrammatically. Fig. 2 is an enlargedsectional view showing details of construction. Fig. 3 is a section onthe line 8 3 of Fig. 2. Fig. 1 is an enlarged section showing the methodof supporting the electrodes from the casing, and Fig. 5 is an enlargedsection on the line 5 5 of Fig. 2.

Like marks of reference refer to similar parts in the several views ofthe drawings.

10 is the inlet-passage, and 11 the outletpassage. The passages 10 and11 are connected by a plurality of imperforate conduits 12. Theseconduits 12 are formed of conducting material and are preferably formedintegral with the passages 10 and 11, as shown in the drawings, so as toobviate the use of joints between the conduits and passages. Leading tothe inlet-passage 10 is a supplypipe 14, in which is situated a valve 15for regulating the flow of water through the purifier. The opposite endof the supply-passage 10 is provided with a valve 16, by means of wh ichthe su pply-passago 10 may be cleaned. The outlet-passage 11 is providedwith a discharge-pipe 17, in which is situated a valve 18 for regulatingthe discharge of water from the purifier. The opposite end of theoutletpassage 11 is provided with a valve 19, by

means of which the outlet-passage 11 may be cleaned. 4 r

.On the inlet-passage 10 are formed, oppo' site the conduit 1 2, shortpipes 21. In each of these pipes 21 is a threaded plug 22, provided witha flange 23. Between this flange 23 and the upper edge of the pipe 21 isa rubber gasket 2 1 or other suitable packing for forming a water-tightjoint between the pipe 21 and the plug. Extending centrally through theplug 22 is an offset opening in which is situated an insulatiug-plug 25,having a shoulder 26. Between this shoulder 26 and thecorrespondingshoulder of the plug 22 is a rubber gasket 27 or othersuitable packing for forming a water-tight joint between the plug 22 andthe insulatingplug Extending through the insulating-plug 25 is the end28 of an electrode 29, which electrode extends through the conduit 12.The end 28 may be formed integral with the electrode 29, but ispreferably threaded therein, as shown in Fig. at of the drawings. Theupper part of this end 28 is threaded and engages with a nut 30, whichbears upon an insulating-washer 3-1, which in turn rests upon the plug22 and surrounds the upper end 'of the insulating-plug 25. By tighteningthe nut 30 the shoulder 26 is drawn firmly against the packing 27, so asto form a water-tight joint between the two plugs and at the same timehold the electrode firmly in position. Above the nut 30 is a second nut32, and between these nuts is a strip 33 of conducting material whichelectrically connects all the electrodes 29.

cured to this strip 33 is a binding-post 34L, to which is connected oneend of a line-wire35, the opposite end of which is connected to abinding-post 36, carried on the inlet-passage 10. Situated in thecircuit 35 is abattery 37 or other source of electricalenergy. Securedto the lower end of each of the electrodes 29 is a rosette 38, ofinsulating material, the shape of which is best shown in Fig. 5. Thisrosette is secured to the lower end of the electrode by means of ascrew39, passing through the said rosette into the electrode, as shown inFig. 2. The shape of the rosette is such as to prevent contact of theelectrode with the conduit and at the same time to allow free flow ofthe water into the outlet-passage 11.

In the operation of my purifier the water passes into the inlet-passage10 through the supply-pipe 14, the flow being regulated by the valve 15.The water then passes down simultaneously through the various conduits12 and issubjected to the action of the current flowing between the saidconduits and the electrodes 29. Owing to the number of conduits used,alarge flow. of water is obtained, and atthe same time the space betweenthe conduit and electrode can be made so small that the water isperfectly purified. The discharge. of the water through the passage 17is regulated by the valve 18. As the inlet and outlet passages 10and 11are formed integral with the conduits 12, there are very few joints inthe purifier, and hence liability of leakage is greatly lessened.Themanner of supporting the electrodes insures a watertight jointbetween the various parts and at the same time firmly holds theelectrode in position.

In place of causing the water to flow in the direction above describedthe inlet and outlet may be reversed, the watenflowing into the manifold11 and thence up through the pipes. into the manifold 10. This mode ofoperation is preferable in case it is desired to run the purifier at,less than its full capacity.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is
